Comments about Including the Disciplinary Core Idea
Probing questions posed in text could be discussed with students, with focus on tsunami formation, prediction, and model development. This discussion would review topics stressed in the Performance Expectation. Students could view tsunami videos that depict the impact of a tsunami on populations and environments. Students could discuss impacts as well as respond to questions posed in text. (Example- If scientists knew that a severe earthquake had occurred in the Indian Ocean, why didn't they warn people?). Discussion of these questions could precede the introduction of the computer/satellite models. Cause and effect of tsunami development and occurring damage could be contrasted with changes in cause/effect impacts when warning systems are put in place. Students could conclude lesson with reflection about their own learning, how their study of earth's processes might help them to be better prepared to reduce the impact of natural disasters.
